I've used regular rum, coconut flavoured rum and 151 proof rum in this recipe and all work great.
VERY IMPORTANT: It is much easier to scoop out a dollop of the dough and dump it into a bowl of confectioners sugar and then scoop it out and roll it into a ball. Otherwise I found it was impossible to get enough sugar on my hands to keep it from sticking. VERY TASTY RECIPE THOUGH. - 30 Nov 2005 (Review from Allrecipes USA and Canada)
I think it includes far too much corn syrup to make it workable. Unfortunately I didn't know this until I attempted to make a double batch. Out of desperation I tried to save the mess by working in 4 cups of confectioners sugar, but the dough was still far too sticky to manage, even after being chilled. - 11 Dec 2005 (Review from Allrecipes USA and Canada)
These are yummy. I didn't realize until I was making them that my 1 package of vanilla wafers was only 12 oz. not 16 oz. Given that, I used less corn syrup so they wouldn't be too sticky. I started with a 1/4 cup and added more until the consisency was right. So make sure your oz. is right on the cookies and adjust corn syrup accordingly. I also couldn't make the sugar coated hands work. I used a cookie scoop to drop into a roll with sugar and rolled them that way. - 26 Dec 2009 (Review from Allrecipes USA and Canada)
